Original post: Between eight and 10 people are believed to be trapped in rubble following a building collapse, possibly as the result of an industrial accident, AP and Philly.com report. Emergency crews are on the scene and have blocked off surrounding roads, local media outlets report.

The building collapsed in Center City at 22nd and Market streets, near the center of Philadelphia. AP reports construction had been happening on the same block. Philly.com also reports “several ambulances have driven away from the scene, sirens blaring.”

The building collapsed around 10:45 this morning and brought down part of a next-door thrift store. Most of the buildings on the block appear to be row homes, WPVI said.
